CLOCK MOVEMENT AND DIAL SUPPORTING MEANS Filed Feb, l, lSZ

...nnnnnnnnn nnn I Patented June 24, 1930 NH'ED rATEN'r OFFICE y JOSEPH WILCOX, JR., OF ATI'IOL, MASSACHUSETTS, ASSIGNOR TO'k WILCOX NOVELTY COMPANY, OF ATI-IOL, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS y CLOCK MOVEMENT AND' DIAL-SUPPORTING MEANS Application lcd February This invention relates to a clock movement of the type used in small clocks such as aref commonly sold for table or mantel use or in toilet sets.. It is desirable that these small clock movements shall constitute complete units which may be easily inserted in any one of an extended line of different cases.

It is the general object of my present invention to provide an improved movement and dial support so constructed that the dial is mounted directly on the movement frame, and the dial and hands may be assembled with the movement before the movement is inserted in the casing.

My improved construction is also such that the dial may be quickly and easily removed when it is necessary to repair or clean the movement.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings in which:

Fig. 1 is a front view of my improved movement and dial; and

Fig. 2 is a side elevation, partly in section, looking in the direct-ion of the arrow 2 in Fig. 1.

Referring to the drawings, I show a clock movement comprising a front movement plate 10, a back movement plate 11, and movement posts 12 which hold the front and back plates in denite spaced relation. Theclock mechanism M is mounted between the movement plates and may be of any usual construction.

The movements posts 12 are preferably formed as indicated in Fig. 2, which shows the rear end of the post 12 as provided with a threaded projection 13 adapted to be riveted into the back plate 11. A tapped hole 14 is formed in the rear end of the post 12 and is'adapted to receive a threaded pin or stud 15, projecting rearwardly therefrom.

A back casing plate 16 is mounted on the studs 15 and is spaced from the back move- 60 ment platek 11 by one or more collars 17 Nuts 18 threaded on the studs 15 secure the back casing plate 16 in position.

At their front ends the movement posts 12 are each provided with a threaded extension 20 projecting through the front movement plate 10. Nuts 21 on the extensions 20rmly retain the plate 10 in position and in definite spaced relation from the plate 11.

The extensions 20 on certain of the posts 12 are threaded at 22 to receive screws 23 extending throu h corresponding openings in the dial 24. ollars 25 may be provided for spacing the dial at a desired distance from the movement plate 10. The dial 24: may be of the oval shape shown in Fig. 1, which is particularly well adapted for attachment in this manner to a clock movement, as the dial may be secured by a three pointV attachment and the several screws 23 are desirably located on the dial face.

Having thus described the details of con-- struction of my improved movement and dial supporting means, it will be seen that the movement and dial constitute a single unit which may be placed in a casing or removed therefrom without removing the hands 26 or otherwise separating the parts.

Furthermore the movement may be inserted as a friction fit within a casing, as is now common, and when thus inserted the back plate 16 already mounted on the movement will close the rear opening of the casing and exclude dirt and dust from the movement.A Whenever it is necessary to clean or repair the movement the dial may be easily removed by taking out the screws 23 and the back plate may be correspondingly removed by taking off the nuts 18.

The dial is secured in an exact predetermined relation'to the movement and hands and there is no chance for the dial to become relatively displaced, thus causing the lards to bind against the opening in the I have thus described my invention and the advantages thereof and I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I do claim is:
